FREQUENTLY ASKED QUESTIONS (FAQ)

1. What is the "Direct Output" gear for? It allows you to quickly switch to common voltages used in mobile repair, such as 3.6V or 4.8V, without manually turning the fine-tuning knobs.

2. Does it have a cooling fan? Yes, it features an intelligent cooling system to dissipate heat during high-load operations.

3. What happens during a short circuit? The protection circuit engages immediately to prevent damage. Most models feature Automatic Recovery, which restores power once the short is removed.

4. Can I charge a dead mobile battery with this? Yes, it is ideal for battery boosting, but you must carefully set the voltage and current according to the battery specifications to avoid damage.

5. Is this suitable for 110V or 220V? Most units are 220V, but they are often selectable or available as 110V versions. Check the rear label before powering on.

6. What is the "Coarse" vs "Fine" knob? The Coarse knob makes large voltage changes, while the Fine knob allows for small, precision adjustments of 0.1V.

7. Can it be used for continuous heavy load? It is recommended to keep the utilization rate below 60% for long-term reliability.

8. What is the maximum current output? The standard YG-1502DD is rated for a maximum of 2A.

9. Can I test GSM signals with this? Yes, it includes a signal strength indicator that can detect transmissions from mobile devices during testing.

10. How do I replace the fuse? The fuse is located in a dedicated compartment near the AC input. Always disconnect power before replacing.

11. Is the display LCD or LED? This model features bright digital LED displays for easy reading in dark workshop environments.

12. Can I use it to power a small motor? Yes, as long as the motor's startup and running current do not exceed the 2A limit.

13. Is it grounded? Yes, the front panel includes a dedicated yellow GND (Grounding) terminal.

14. What is the voltage accuracy? It typically has a display accuracy of 0.1V.

15. Does it support Constant Current (CC) mode? Yes, it allows for current limiting (CC) adjustment, especially useful when powering up a board for the first time.

16. How portable is the unit? It weighs approximately 1.6kg and has compact dimensions, making it easy to move around a workbench.

17. Can I use it for laptop repair? It is mostly suited for smaller devices; high-end laptops may require a 19V-20V / 5A+ supply.

18. Are the test leads included? Yes, a standard package includes output test cables.

19. What is the input frequency? It operates on standard 50Hz/60Hz AC power.

20. Is it safe for children to use? It should only be used by children aged 8+ under adult supervision due to high voltage risks.
